Session creation method and apparatus, and electronic device

A session creation method, performed by a third electronic device, comprising:

• while a first electronic device and N second electronic devices are participating in a first Session Initiation Protocol (SIP) session, receiving a first reference (REFER) request by the third electronic device from the first electronic device, wherein the first REFER request is used for requesting to create a second SIP session, which is separate and distinct from the first SIP session, between the first electronic device and the third electronic device, wherein the third electronic device is among the N second electronic devices participating in the first SIP session with the first electronic device, and N is a positive integer that is greater than 1;
• and
• sending, by the third electronic device, a first response message to the first electronic device in response to the first REFER request, wherein the first response message is used for indicating whether the third electronic device agrees to create the second SIP session, wherein
• after the second SIP session is created, the first electronic device and the third electronic device are simultaneously participating both the first and second SIP sessions, so that the first electronic device outputs an audio signal to both the first and second SIP sessions simultaneously.

A first electronic device comprising:

• a memory having a computer program stored thereon;
• and a processor, wherein the computer program, when executed by the processor, causes the processor to perform a session creation method, comprising:
• while a first electronic device and N second electronic devices are participating in a first Session Initiation Protocol (SIP) session, sending a first reference (REFER) request by the first electronic device to a third electronic device, wherein the first REFER request is used for requesting to create a second SIP session, which is separate and distinct from the first SIP session, between the first electronic device and the third electronic device, wherein the third electronic device is among the N second electronic devices participating in the first SIP session with the first electronic device and N is a positive integer that is greater than 1;
• receiving, by the first electronic device, a first response message fed back by the third electronic device in response to the first REFER request;
• and
• creating, by the first electronic device, the second SIP session when the first response message received that the third electronic device agrees to create the second SIP session, wherein
• after creating the second SIP session, the first electronic device and the third electronic device are simultaneously participating both the first and second SIP sessions, so that the first electronic device outputs an audio signal to both the first and second SIP sessions simultaneously.
